We are in the Insurance business and do a lot of 2 sided copies. This paper is heavy enough not to curl or cause jams. The only problem is there is usually a limit on the number of cases you are allowed to purchase at a time. It's expensive but well worth it.
I recommend this papers for better printing results than any other brand and type. 98 is a brightest and excellent paper. Too bad it is expensive but it is still a great value if you want excellent prints.
